A short note on Space exploration

The Space exploration is the physical exploration of outer-Earth objects and in general anything that involves the technologies, science, and politics about the space endeavors.
It was given a boost up by the start of Sputnik 1, the first man-made object to orbit the Earth, which set off the space race involving the United States and the Soviet Union. The Two other well-known achievements in the early days were putting the first man in space, the Yuri Gagarin aboard Vostok 1, and the first people on the Moon, the Neil Armstrong and Buzz Aldrin aboard Apollo 11. After 30 years of rivalry focus has started shifting from competition to help and from the one-off flights to renewable hardware and most lately to the building of extra-terrestrial start on platforms, like from a space station and perhaps from the Moon.
